I could see a series that's more detective-style going after the rich people who run it or whatever, but it wouldn't be metaphorical in the same way. Unless maybe he decides to simply rejoin the game but uses it to do a squid-revolution. But Squid Game is mainly interesting because it's a novel premise like battle royale or whatever. Would have to lose all his money or something to make it interesting though.
